Guess who’s turning 50 this year. Havaianas! And what an accomplished 50 years it’s been. The little Brazilian shoe company that could has become the fast-footwear brand that did. And as long as we’re comparing Havaianas to McDonald’s, over four billion pairs have been sold. Four billion! That comes to 190 million pairs per year, 520,547 pairs per day, 21,689 pairs per hour, 6 pairs per second. So here’s to you, funny rubber sandals from the equator. We really couldn’t live without you.
